Abstract (en)
Provided are a fingerprint identification apparatus and an electronic device. The fingerprint identification apparatus includes: a micro lens array; at least one light shielding layer; a pixel unit array; and an array of filter unit groups, where each filter unit group in the array of filter unit groups includes at least two filter units, and the at least two filter units are configured to transmit light signals in at least two colors respectively, where the pixel unit array includes a pixel unit group corresponding to the filter unit group, at least two pixel units in the pixel unit group receive a first light signal through the at least two filter units respectively, and a pixel unit except the at least two pixel units in the pixel unit group receives a second light signal through a transparent region between the at least two filter units, or a pixel unit between pixel unit groups receives the second light signal through a transparent region between the filter unit groups. The fingerprint identification apparatus can improve the security of fingerprint identification without affecting the fingerprint identification effect.
